The PS2561L-1-L-A is an optoisolator device which relies on photovoltaic output and a transistor to create an electrical insulating barrier between two circuits. This optoisolator combines optical and electrical isolation, enabling the safe and reliable transmission of electrical signals in applications which would be otherwise potentially hazardous. As an optically coupled isolator, it is widely employed in many industries such as the automotive, medical, and industrial automation fields.

The electric circuit portion of the PS2561L-1-L-A consists of an LED and a gallium arsenide-infrared phototransistor. It has a CTR of over 500% indicated by its PS2561 designation. This optoisolator is specifically manufactured to meet the standards of the safety approval agencies like VCCI, CCC, EN55022, BSMI, etc., and has been tested to meet high-temperature range up to 85 degrees Celsius.

The functioning of the PS2561L-1-L-A is that the LED element emits optical radiation which is picked up by the phototransistor. This produces a current that is proportionately amplified by the transistor to bring about the desired output, while maintaining an electrically isolated barrier between the two circuits. The efficiency rate of this optoisolator is indicated by the words "optically coupled" in its name.

The primary application of PS2561L-1-L-A is in controlling motors, relays, transformer circuits, and other equipment that require signals amplification.
